Williams Sound Personal P.A. T18, Инструкция по установке и эксплуатации

Страница: 10 / 17

Symptom: Scratchy noise when receiver volume control is adjusted.
Remedy: 1. Open the back of the receiver case by opening the battery compartment. Keep lifting on
the battery door and the back of the receiver case will open like a book.
2. Remove the screw from the center of the volume control and remove the knob.
3. Lift the clear plastic cover on the control and spray GC SPRA-KLEEN, LPS Contact
Cleaner, or equivalent into the control. Replace the knob and rotate the control several
times.
4. Replace the screw and close the case.
Symptom: Buzzing or humming noise in sound system.
Remedies: 1. There is nothing wrong with the T18 Transmitter. One or more pieces of equipment in
the sound system are being disturbed by RF (Radio Frequency) signals produced by the
T18. The most likely suspects are your amplifier, mixer, or tape deck. The RF gets into
the other equipment primarily through the power cord, speaker wires, or unshielded
inputs, all of which can act as antennas.
Try moving the Transmitter away from the other sound equipment.
2. If remedy 1 does not solve the problem, we recommend using the optional Coax
Antenna (ANT 005), which should be located 15-20 feet away from the other sound
equipment. You may add additional RG-59 feedline, as needed.
4. If changing the Coax Antenna doesn’t help, it’s time to dig deeper into the problem. This
involves a slight modification to the equipment that’s causing the problem. Unless you
have the necessary technical skills, this is best left to a qualified electronics repair
technician. Call your Authorized Dealer or Williams Sound Corp. for more information.
